The origins of this expression goes long into the history books. The first translation of this latin proverb ‘Fertilior seges est alienosemper in arvo’ into English, was published in 1545 ‘The corne in an other mans ground semetheuer more fertyll and plentifull then doth oureowne’. Though ironically, optical and perceptual laws alone will make the grass at a distance look greener to the human eye than the blades of grass perpendicular to the ground - and that’s no bullshit.
